<h:button>
The <h:button>
generates a HTML <input type="button">
. The generated element uses JavaScript to navigate to the page given by the attribute outcome
, using a HTTP GET request.
E.g.
<h:button value="GET button" outcome="otherpage" />
will generate
<input type="button" onclick="window.location.href='/contextpath/otherpage.xhtml'; return false;" value="GET button" />
Even though this ends up in a (bookmarkable) URL change in the browser address bar, this is not SEO-friendly. Searchbots won't follow the URL in the onclick
. You'd better use a <h:outputLink>
or <h:link>
if SEO is important on the given URL. You could if necessary throw in some CSS on the generated HTML <a>
element to make it to look like a button.
Do note that while you can put an EL expression referring a method in outcome
attribute as below,
<h:button value="GET button" outcome="#{bean.getOutcome()}" />
it will not be invoked when you click the button. Instead, it is already invoked when the page containing the button is rendered for the sole purpose to obtain the navigation outcome to be embedded in the generated onclick
code. If you ever attempted to use the action method syntax as in outcome="#{bean.action}"
, you would already be hinted by this mistake/misconception by facing a javax.el.ELException: Could not find property actionMethod in class com.example.Bean.
If you intend to invoke a method as result of a POST request, use <h:commandButton>
instead, see below. Or if you intend to invoke a method as result of a GET request, head to Invoke JSF managed bean action on page load or if you also have GET request parameters via <f:param>
, How do I process GET query string URL parameters in backing bean on page load?
<h:commandButton>
The <h:commandButton>
generates a HTML <input type="submit">
button which submits by default the parent <h:form>
using HTTP POST method and invokes the actions attached to action
, actionListener
and/or <f:ajax listener>
, if any. The <h:form>
is required.
E.g.
<h:form id="form">
<h:commandButton id="button" value="POST button" action="otherpage" />
</h:form>
will generate
<form id="form" name="form" method="post" action="/contextpath/currentpage.xhtml" enctype="application/x-www-form-urlencoded">
<input type="hidden" name="form" value="form" />
<input type="submit" name="form:button" value="POST button" />
<input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="...." autocomplete="off" />
</form>
Note that it thus submits to the current page (the form action URL will show up in the browser address bar). It will afterwards forward to the target page, without any change in the URL in the browser address bar. You could add ?faces-redirect=true
parameter to the outcome value to trigger a redirect after POST (as per the Post-Redirect-Get pattern) so that the target URL becomes bookmarkable.
The <h:commandButton>
is usually exclusively used to submit a POST form, not to perform page-to-page navigation. Normally, the action
points to some business action, such as saving the form data in DB, which returns a String
outcome.
<h:commandButton ... action="#{bean.save}" />
with
public String save() {
// ...
return "otherpage";
}
Returning null
or void
will bring you back to the same view. Returning an empty string also, but it would recreate any view scoped bean. These days, with modern JSF2 and <f:ajax>
, more than often actions just return to the same view (thus, null
or void
) wherein the results are conditionally rendered by ajax.
public void save() {
// ...
}
Lets say you saved your software onto your desktop.
if you want to remove an entire folder like an uninstaller program you could use this.
cd C:\Users\User\Detsktop\
rd /s /q SOFTWARE
this will delete the entire folder called software and all of its files and subfolders

Copying Will's comment into an answer, because I found it useful:
var string = "this is a string";
var length = 20;
var trimmedString = string.length > length ?
string.substring(0, length - 3) + "..." :
string;
Thanks Will.

Without changing the position to absolute, see below. This supports all recent browsers as well.
.vranger {_x000D_
margin-top: 50px;_x000D_
transform: rotate(270deg);_x000D_
-moz-transform: rotate(270deg); /*do same for other browsers if required*/_x000D_
}
_x000D_
<input type="range" class="vranger"/>
_x000D_
for very old browsers, you can use -sand-transform: rotate(10deg);
from CSS sandpaper
or use
prefix selector such as -ms-transform: rotate(270deg);
for IE9
If you are not using any javascript/jquery for form validation, then a simple layout for your form would look like this.
within the body of your html document:
<form action="formHandler.php" name="yourForm" id="theForm" method="post">
<input type="text" name="fname" id="fname" />
<input type="submit" value="submit"/>
</form>
You need to ensure you have the submit button within the form tags, and an appropriate action assigned. Such as sending to a php file.

I installed ArcGIS Pro 1.4 and it didn't register the Python 3.5.2 it installed which prevented me from installing any add-ons. I resolved this by using the "reg" command in an Administrator PowerShell session to manually create and populate the necessary registry keys/values (where Python is installed in C:\Python35):
reg add "HKLM\Software\Python\PythonCore\3.5\Help\Main Python Documentation" /reg:64 /ve /t REG_SZ /d "C:\Python35\Doc\Python352.chm"
reg add "HKLM\Software\Python\PythonCore\3.5\InstallPath" /reg:64 /ve /t REG_SZ /d "C:\Python35\"
reg add "HKLM\Software\Python\PythonCore\3.5\InstallPath\InstallGroup" /reg:64 /ve /t REG_SZ /d "Python 3.5"
reg add "HKLM\Software\Python\PythonCore\3.5\PythonPath" /reg:64 /ve /t REG_SZ /d "C:\Python35\Lib;C:\Python35\DLLs;C:\Python35\Lib\lib-tk"
I find this easier than using Registry Editor but that's solely a personal preference.
The same commands can be executed in CMD.EXE session if you prefer; just make sure you run it as Administrator.

Suppose you have this file:
$ cat /tmp/test.txt
Line 1
Line 2 has leading space
Line 3 followed by blank line
Line 5 (follows a blank line) and has trailing space
Line 6 has no ending CR
There are four elements that will alter the meaning of the file output read by many Bash solutions:
If you want the text file line by line including blank lines and terminating lines without CR, you must use a while loop and you must have an alternate test for the final line.
Here are the methods that may change the file (in comparison to what cat
returns):
1) Lose the last line and leading and trailing spaces:
$ while read -r p; do printf "%s\n" "'$p'"; done </tmp/test.txt
'Line 1'
'Line 2 has leading space'
'Line 3 followed by blank line'
''
'Line 5 (follows a blank line) and has trailing space'
(If you do while IFS= read -r p; do printf "%s\n" "'$p'"; done </tmp/test.txt
instead, you preserve the leading and trailing spaces but still lose the last line if it is not terminated with CR)
2) Using process substitution with cat
will reads the entire file in one gulp and loses the meaning of individual lines:
$ for p in "$(cat /tmp/test.txt)"; do printf "%s\n" "'$p'"; done
'Line 1
Line 2 has leading space
Line 3 followed by blank line
Line 5 (follows a blank line) and has trailing space
Line 6 has no ending CR'
(If you remove the "
from $(cat /tmp/test.txt)
you read the file word by word rather than one gulp. Also probably not what is intended...)
The most robust and simplest way to read a file line-by-line and preserve all spacing is:
$ while IFS= read -r line || [[ -n $line ]]; do printf "'%s'\n" "$line"; done </tmp/test.txt
'Line 1'
' Line 2 has leading space'
'Line 3 followed by blank line'
''
'Line 5 (follows a blank line) and has trailing space '
'Line 6 has no ending CR'
If you want to strip leading and trading spaces, remove the IFS=
part:
$ while read -r line || [[ -n $line ]]; do printf "'%s'\n" "$line"; done </tmp/test.txt
'Line 1'
'Line 2 has leading space'
'Line 3 followed by blank line'
''
'Line 5 (follows a blank line) and has trailing space'
'Line 6 has no ending CR'
(A text file without a terminating \n
, while fairly common, is considered broken under POSIX. If you can count on the trailing \n
you do not need || [[ -n $line ]]
in the while
loop.)

If you can make an approximation of the number of items that will be there at the end, use the overload of the List constuctor that takes count as a parameter. You will save some expensive List duplications. Otherwise you have to pay for it.
When you generate a JAXB model from an XML Schema, global elements that correspond to named complex types will have that metadata captured as an @XmlElementDecl
annotation on a create method in the ObjectFactory
class. Since you are creating the JAXBContext
on just the DocumentType
class this metadata isn't being processed. If you generated your JAXB model from an XML Schema then you should create the JAXBContext
on the generated package name or ObjectFactory
class to ensure all the necessary metadata is processed.
Example solution:
JAXBContext jaxbContext = JAXBContext.newInstance(my.generatedschema.dir.ObjectFactory.class);
DocumentType documentType = ((JAXBElement<DocumentType>) jaxbContext.createUnmarshaller().unmarshal(inputStream)).getValue();
I think this is a file problem, you simple saved your file in 1-byte encoding like latin-1. Google up your editor and how to set files to utf-8.
I wonder why there are editors that don't default to utf-8.
2 ways:-
1st one Custom Query
@Modifying
@Query("delete from User where firstName = :firstName")
void deleteUsersByFirstName(@Param("firstName") String firstName);
2nd one JPA Query by method
List<User> deleteByLastname(String lastname);
When you go with query by method (2nd way) it will first do a get call
select * from user where last_name = :firstName
Then it will load it in a List Then it will call delete id one by one
delete from user where id = 18
delete from user where id = 19
First fetch list of object, then for loop to delete id one by one
But, the 1st option (custom query),
It's just a single query It will delete wherever the value exists.

Removing the '^' did it for me. I'm looking at a varchar field and when I included the ^ it excluded all of my non-numerics which is exactly what I didn't want. So, by removing ^ I only got non-numeric values back.
Though this question already has sufficient answers, I thought somebody would want to know why this flag works in this peculiar manner, This is what I found in Android documentation
The currently running instance of activity B in the above example will either receive the new intent you are starting here in its onNewIntent() method, or be itself finished and restarted with the new intent.
If it has declared its launch mode to be "multiple" (the default) and you have not set FLAG_ACTIVITY_SINGLE_TOP in the same intent, then it will be finished and re-created; for all other launch modes or if FLAG_ACTIVITY_SINGLE_TOP is set then this Intent will be delivered to the current instance's onNewIntent().
So, Either,
1. Change the launchMode
of the Activity A to something else from standard (ie. singleTask
or something). Then your flag FLAG_ACTIVITY_CLEAR_TOP
will not restart your Activity A.
or,
2. Use Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP
as your flag. Then it will work the way you desire.
You can also try the randomcoloR
package:
library(randomcoloR)
n <- 20
palette <- distinctColorPalette(n)
You can see that a set of highly distinct colors are chosen when visualizing in a pie chart (as suggested by other answers here):
pie(rep(1, n), col=palette)
Shown in a pie chart with 50 colors:
n <- 50
palette <- distinctColorPalette(n)
pie(rep(1, n), col=palette)
Sometimes you need to see version of mongodb after making a connection from your project/application/code. In this case you can follow like this:
mongoose.connect(
encodeURI(DB_URL), {
keepAlive: true
},
(err) => {
if (err) {
console.log(err)
}else{
const con = new mongoose.mongo.Admin(mongoose.connection.db)
con.buildInfo( (err, db) => {
if(err){
throw err
}
// see the db version
console.log(db.version)
})
}
}
)

Using .innerText
should work.
document.getElementById('lbltipAddedComment').innerText = 'your tip has been submitted!';
This will give you sequence of anonymous objects, containing date string and two properties with average price:
var query = from p in PriceLogList
group p by p.LogDateTime.ToString("MMM yyyy") into g
select new {
LogDate = g.Key,
AvgGoldPrice = (int)g.Average(x => x.GoldPrice),
AvgSilverPrice = (int)g.Average(x => x.SilverPrice)
};
If you need to get list of PriceLog objects:
var query = from p in PriceLogList
group p by p.LogDateTime.ToString("MMM yyyy") into g
select new PriceLog {
LogDateTime = DateTime.Parse(g.Key),
GoldPrice = (int)g.Average(x => x.GoldPrice),
SilverPrice = (int)g.Average(x => x.SilverPrice)
};
^
matches position just before the first character of the string$
matches position just after the last character of the string.
matches a single character. Does not matter what character it is, except newline*
matches preceding match zero or more timesSo, ^.*$
means - match, from beginning to end, any character that appears zero or more times. Basically, that means - match everything from start to end of the string. This regex pattern is not very useful.
Let's take a regex pattern that may be a bit useful. Let's say I have two strings The bat of Matt Jones
and Matthew's last name is Jones
. The pattern ^Matt.*Jones$
will match Matthew's last name is Jones
. Why? The pattern says - the string should start with Matt and end with Jones and there can be zero or more characters (any characters) in between them.
Feel free to use an online tool like https://regex101.com/ to test out regex patterns and strings.
Also, if, like me, you add controls directly in XAML (not using the editor), you might get frustrated that it won't stretch to the available height, even after setting those two properties.
To make the TextBox stretch, set the Height="Auto"
.
UPDATE:
In retrospect, I think this must have been necessary thanks to a default style for TextBoxes specifying the height to some standard for the application somewhere in the App resources. It may be worthwhile checking this if this helped you.
I ran into this when updating an entity with a JSON post request. The error occurred when I updated the entity without data about the children, even when there were none. Adding
"children": [],
to the request body solved the problem.
The correct format for IE8 is:
$("#ActionBox").css({ 'margin-top': '10px' });
with this work.
You could just nest the Text components with the required style. The style will be applied along with already defined style in the first Text component.
Example:
<Text style={styles.paragraph}>
Trouble singing in. <Text style={{fontWeight: "bold"}}> Resolve</Text>
</Text>
If you want the script to run in the current shell (e.g. you want it to be able to affect your directory or environment) you should say:
. /path/to/script.sh
or
source /path/to/script.sh
Note that /path/to/script.sh
can be relative, for instance . bin/script.sh
runs the script.sh
in the bin
directory under the current directory.

Use SimpleCrypto
Using encrypt() and decrypt()
To use SimpleCrypto, first create a SimpleCrypto instance with a secret key (password). Secret key parameter MUST be defined when creating a SimpleCrypto instance.
To encrypt and decrypt data, simply use encrypt() and decrypt() function from an instance. This will use AES-CBC encryption algorithm.
var _secretKey = "some-unique-key";
var simpleCrypto = new SimpleCrypto(_secretKey);
var plainText = "Hello World!";
var chiperText = simpleCrypto.encrypt(plainText);
console.log("Encryption process...");
console.log("Plain Text : " + plainText);
console.log("Cipher Text : " + cipherText);
var decipherText = simpleCrypto.decrypt(cipherText);
console.log("... and then decryption...");
console.log("Decipher Text : " + decipherText);
console.log("... done.");
TL;DR Use absolute paths to your assets (including your complete hostname) by setting your output.publicPath
to e.g. "http://example.com/assets/".
The problem is the way that URLs are resolved by Chrome when they're parsed from a dynamically loaded CSS blob.
When you load the page, the browser loads your Webpack bundle entry JavaScript file, which (when you're using the style-loader
) also contains a Base64 encoded copy of your CSS, which gets loaded into the page.
That's fine for all the images or fonts which are encoded into the CSS as data URIs (i.e. the content of the file is embedded in the CSS), but for assets referenced by URL, the browser has to find and fetch the file.
Now by default the file-loader
(which url-loader
delegates to for large files) will use relative URLs to reference assets - and that's the problem!
These are the URLs generated by
file-loader
by default - relative URLs
When you use relative URLs, Chrome will resolve them relative to the containing CSS file. Ordinarily that's fine, but in this case the containing file is at blob://...
and any relative URLs are referenced the same way. The end result is that Chrome attempts to load them from the parent HTML file, and ends up trying to parse the HTML file as the content of the font, which obviously won't work.
Force the file-loader
to use absolute paths including the protocol ("http" or "https").
Change your webpack config to include something equivalent to:
{
output: {
publicPath: "http://localhost:8080/", // Development Server
// publicPath: "http://example.com/", // Production Server
}
}
Now the URLs that it generates will look like this:
These URLs will be correctly parsed by Chrome and every other browser.
extract-text-webpack-plugin
It's worth noting that if you're extracting your CSS to a separate file, you won't have this problem because your CSS will be in a proper file and URLs will be correctly resolved.
A little intro to dictionary
d={'a':'apple','b':'ball'}
d.keys() # displays all keys in list
['a','b']
d.values() # displays your values in list
['apple','ball']
d.items() # displays your pair tuple of key and value
[('a','apple'),('b','ball')
Print keys,values method one
for x in d.keys():
print x +" => " + d[x]
Another method
for key,value in d.items():
print key + " => " + value
You can get keys using iter
>>> list(iter(d))
['a', 'b']
You can get value of key of dictionary using get(key, [value])
:
d.get('a')
'apple'
If key is not present in dictionary,when default value given, will return value.
d.get('c', 'Cat')
'Cat'

Not what I was after, but another commercial product (much like Highcharts) is TeeChart.
You could create an extension method to add all property values through reflection:
public static DataSet ToDataSet<T>(this IList<T> list)
{
Type elementType = typeof(T);
DataSet ds = new DataSet();
DataTable t = new DataTable();
ds.Tables.Add(t);
//add a column to table for each public property on T
foreach(var propInfo in elementType.GetProperties())
{
t.Columns.Add(propInfo.Name, propInfo.PropertyType);
}
//go through each property on T and add each value to the table
foreach(T item in list)
{
DataRow row = t.NewRow();
foreach(var propInfo in elementType.GetProperties())
{
row[propInfo.Name] = propInfo.GetValue(item, null);
}
}
return ds;
}
I hope I'm not late to the party.. Here is my answer. I like using Pattern/Matcher because it uses regex which should be more efficient. Yet, I think this answer could be enhanced:
Matcher matcher = Pattern.compile("is").matcher("I think there is a smarter solution, isn't there?");
int numOfOcurrences = 2;
for(int i = 0; i < numOfOcurrences; i++) matcher.find();
System.out.println("Index: " + matcher.start());
this my solution:
json string $columns_validation = string(1736) "[{"colId":"N_ni","hide":true,"aggFunc":null,"width":136,"pivotIndex":null,"pinned":null,"rowGroupIndex":null},{"colId":"J_2_fait","hide":true,"aggFunc":null,"width":67,"pivotIndex":null,"pinned":null,"rowGroupIndex":null}]"
so i use json_decode twice like that :
$js_column_validation = json_decode($columns_validation);
$js_column_validation = json_decode($js_column_validation);
var_dump($js_column_validation);
and the result is :
array(15) { [0]=> object(stdClass)#23 (7) { ["colId"]=> string(4) "N_ni" ["hide"]=> bool(true) ["aggFunc"]=> NULL ["width"]=> int(136) ["pivotIndex"]=> NULL ["pinned"]=> NULL ["rowGroupIndex"]=> NULL } [1]=> object(stdClass)#2130 (7) { ["colId"]=> string(8) "J_2_fait" ["hide"]=> bool(true) ["aggFunc"]=> NULL ["width"]=> int(67) ["pivotIndex"]=> NULL ["pinned"]=> NULL ["rowGroupIndex"]=> NULL }
Below is the only CORRECT algorithm for converting sRGB images, as used in browsers etc., to grayscale.
It is necessary to apply an inverse of the gamma function for the color space before calculating the inner product. Then you apply the gamma function to the reduced value. Failure to incorporate the gamma function can result in errors of up to 20%.
For typical computer stuff, the color space is sRGB. The right numbers for sRGB are approx. 0.21, 0.72, 0.07. Gamma for sRGB is a composite function that approximates exponentiation by 1/(2.2). Here is the whole thing in C++.
// sRGB luminance(Y) values
const double rY = 0.212655;
const double gY = 0.715158;
const double bY = 0.072187;
// Inverse of sRGB "gamma" function. (approx 2.2)
double inv_gam_sRGB(int ic) {
double c = ic/255.0;
if ( c <= 0.04045 )
return c/12.92;
else
return pow(((c+0.055)/(1.055)),2.4);
}
// sRGB "gamma" function (approx 2.2)
int gam_sRGB(double v) {
if(v<=0.0031308)
v *= 12.92;
else
v = 1.055*pow(v,1.0/2.4)-0.055;
return int(v*255+0.5); // This is correct in C++. Other languages may not
// require +0.5
}
// GRAY VALUE ("brightness")
int gray(int r, int g, int b) {
return gam_sRGB(
rY*inv_gam_sRGB(r) +
gY*inv_gam_sRGB(g) +
bY*inv_gam_sRGB(b)
);
}
I use this one:
LocationManager.requestLocationUpdates(String provider, long minTime, float minDistance, LocationListener listener)
For example, using a 1s interval:
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);
the time is in milliseconds, the distance is in meters.
This automatically calls:
public void onLocationChanged(Location location) {
//Code here, location.getAccuracy(), location.getLongitude() etc...
}
I also had these included in the script but didnt actually use them:
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
In short:
public class GPSClass implements LocationListener {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
Log.i("Message: ","Location changed, " + location.getAccuracy() + " , " + location.getLatitude()+ "," + location.getLongitude());
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);
}
}
Mono comes with a wrapper, use theirs!
https://github.com/mono/mono/tree/master/mcs/class/Mono.Data.Sqlite/Mono.Data.Sqlite_2.0 gives code to wrap the actual SQLite dll ( http://www.sqlite.org/sqlite-shell-win32-x86-3071300.zip found on the download page http://www.sqlite.org/download.html/ ) in a .net friendly way. It works on Linux or Windows.

The 'u' in front of the string values means the string is a Unicode string. Unicode is a way to represent more characters than normal ASCII can manage. The fact that you're seeing the u
means you're on Python 2 - strings are Unicode by default on Python 3, but on Python 2, the u
in front distinguishes Unicode strings. The rest of this answer will focus on Python 2.
You can create a Unicode string multiple ways:
>>> u'foo'
u'foo'
>>> unicode('foo') # Python 2 only
u'foo'
But the real reason is to represent something like this (translation here):

For the most part, Unicode and non-Unicode strings are interoperable on Python 2.
There are other symbols you will see, such as the "raw" symbol r
for telling a string not to interpret backslashes. This is extremely useful for writing regular expressions.
>>> 'foo\"'
'foo"'
>>> r'foo\"'
'foo\\"'
Unicode and non-Unicode strings can be equal on Python 2:
>>> bird1 = unicode('unladen swallow')
>>> bird2 = 'unladen swallow'
>>> bird1 == bird2
True
but not on Python 3:
>>> x = u'asdf' # Python 3
>>> y = b'asdf' # b indicates bytestring
>>> x == y
False
findViewById(R.id.android_text) does not need typecasting.
Same thing happend to me after upgrading distro.
Running sudo apt-get install php7.0-mysql
fixed it for me.
string InstallPath = (string)Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\MyApplication\AppPath", "Installed", null);
if (InstallPath != null)
{
// Do stuff
}
That code should get your value. You'll need to be
using Microsoft.Win32;
for that to work though.
If the bytes use an appropriate character encoding already; you could print them directly:
sys.stdout.buffer.write(data)
or
nwritten = os.write(sys.stdout.fileno(), data) # NOTE: it may write less than len(data) bytes
I've used a few CSS hacks and targeted Chrome/Safari/Firefox/IE individually, as each browser renders selects a bit differently. I've tested on all browsers except IE.
For Safari/Chrome, set the height
and line-height
you want for your <select />
.
For Firefox, we're going to kill Firefox's default padding and border, then set our own. Set padding to whatever you like.
For IE 8+, just like Chrome, we've set the height
and line-height
properties. These two media queries
can be combined. But I kept it separate for demo purposes. So you can see what I'm doing.
Please note, for the height/line-height
property to work in Chrome/Safari OSX, you must set the background
to a custom value. I changed the color in my example.
Here's a jsFiddle of the below: http://jsfiddle.net/URgCB/4/
For the non-hack route, why not use a custom select plug-in via jQuery? Check out this: http://codepen.io/wallaceerick/pen/ctsCz
HTML:
<select>
<option>Here's one option</option>
<option>here's another option</option>
</select>
CSS:
@media screen and (-webkit-min-device-pixel-ratio:0) { /*safari and chrome*/
select {
height:30px;
line-height:30px;
background:#f4f4f4;
}
}
select::-moz-focus-inner { /*Remove button padding in FF*/
border: 0;
padding: 0;
}
@-moz-document url-prefix() { /* targets Firefox only */
select {
padding: 15px 0!important;
}
}
@media screen\0 { /* IE Hacks: targets IE 8, 9 and 10 */
select {
height:30px;
line-height:30px;
}
}
You can even use this:
var B = document.body,
H = document.documentElement,
height
if (typeof document.height !== 'undefined') {
height = document.height // For webkit browsers
} else {
height = Math.max( B.scrollHeight, B.offsetHeight,H.clientHeight, H.scrollHeight, H.offsetHeight );
}
or in a more jQuery way (since as you said jQuery doesn't lie) :)
Math.max($(document).height(), $(window).height())
Thanks Antonio,
I've just added the lists
command at the end so it will only return one array with key and count:
Laravel 4
$user_info = DB::table('usermetas')
->select('browser', DB::raw('count(*) as total'))
->groupBy('browser')
->lists('total','browser');
Laravel 5.1
$user_info = DB::table('usermetas')
->select('browser', DB::raw('count(*) as total'))
->groupBy('browser')
->lists('total','browser')->all();
Laravel 5.2+
$user_info = DB::table('usermetas')
->select('browser', DB::raw('count(*) as total'))
->groupBy('browser')
->pluck('total','browser')->all();
You'll want to use the clone()
method in order to get a deep copy of the element:
$(function(){
var $button = $('.button').clone();
$('.package').html($button);
});
Full demo: http://jsfiddle.net/3rXjx/
From the jQuery docs:
The .clone() method performs a deep copy of the set of matched elements, meaning that it copies the matched elements as well as all of their descendant elements and text nodes. When used in conjunction with one of the insertion methods, .clone() is a convenient way to duplicate elements on a page.
I would also like to add something here that if you load desired form that contain tooltip controll before the program's run then tool tip control on that form will not work as described below...
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
objfrmmain = new Frm_Main();
Showtop();//this is procedure in program.cs to load an other form, so if that contain's tool tip control then it will not work
Application.Run(objfrmmain);
}
so I solved this problem by puting following code in Fram_main_load event procedure like this
private void Frm_Main_Load(object sender, EventArgs e)
{
Program.Showtop();
}
You can use jsdom
const jsdom = require("jsdom");
const { JSDOM } = jsdom;
const { document } = (new JSDOM(`...`)).window;
or, take a look at cheerio, it may more suitable in your case.
You could use jQuery to add an event listener on the document DOM.
$(document).on("click", function () {_x000D_
console.log('clicked');_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
_x000D_
Right click on the breakpoint works fine for me (though mostly I am using it for conditional breakpoints on specific variable values. Even breaking on expressions involving a thread name works which is very useful if you're trying to spot threading issues).
To enable production mode in angular 6.X.X Just go to environment file
Like this path
Your path: project>\src\environments\environment.ts
Change production: false
from :
export const environment = {
production: false
};
To
export const environment = {
production: true
};
Try using:
string ap = c.Request["AP"];
That reads from the cookies, form, query string or server variables.
Alternatively:
string ap = c.Request.Form["AP"];
to just read from the form's data.
A method for future reference is something like this. bannedphraseform is the first form and expectedphraseform is the second. If the first one is hit, the second one is skipped (which is a reasonable assumption in this case):
if request.method == 'POST':
bannedphraseform = BannedPhraseForm(request.POST, prefix='banned')
if bannedphraseform.is_valid():
bannedphraseform.save()
else:
bannedphraseform = BannedPhraseForm(prefix='banned')
if request.method == 'POST' and not bannedphraseform.is_valid():
expectedphraseform = ExpectedPhraseForm(request.POST, prefix='expected')
bannedphraseform = BannedPhraseForm(prefix='banned')
if expectedphraseform.is_valid():
expectedphraseform.save()
else:
expectedphraseform = ExpectedPhraseForm(prefix='expected')
This is an old thread but just in case anyone comes across it like I did. pi.FileName needs to be set to the file name (and possibly full path to file ) of the executable you want to use to open your file. The below code works for me to open a video file with VLC.
var path = files[currentIndex].fileName;
var pi = new ProcessStartInfo(path)
{
Arguments = Path.GetFileName(path),
UseShellExecute = true,
WorkingDirectory = Path.GetDirectoryName(path),
FileName = "C:\\Program Files (x86)\\VideoLAN\\VLC\\vlc.exe",
Verb = "OPEN"
};
Process.Start(pi)
Tigran's answer works but will use windows' default application to open your file, so using ProcessStartInfo may be useful if you want to open the file with an application that is not the default.
The much simpler method is to use the decode
method of Integer
so for example:
int helloInt = Integer.decode(hello);
you are using a smart quote “
instead of "
here:
git.exe clone -v “ssh://
^^^
Make sure you use the plain-old-double-quote.
public class StringReverse {
public static void main(String[] args) {
String s= (args[0]);
for (int i =s.length()-1; i >= 0; i--) {
System.out.print(s.charAt(i));
}
}
}
Prints the reversed string of the input.
In newer versions of Eclipse that use the M2E plugin it is:
Right-click on your project(s) --> Maven --> Update Project...
In the following dialog is a checkbox for forcing the update ("Force Update of Snapshots/Releases")
Last or next date, week, month & year calculation. It might be helpful for anyone.
Current Date:
select curdate();
Yesterday:
select subdate(curdate(), 1)
Tomorrow:
select adddate(curdate(), 1)
Last 1 week:
select between subdate(curdate(), 7) and subdate(curdate(), 1)
Next 1 week:
between adddate(curdate(), 7) and adddate(curdate(), 1)
Last 1 month:
between subdate(curdate(), 30) and subdate(curdate(), 1)
Next 1 month:
between adddate(curdate(), 30) and adddate(curdate(), 1)
Current month:
subdate(curdate(),day(curdate())-1) and last_day(curdate());
Last 1 year:
between subdate(curdate(), 365) and subdate(curdate(), 1)
Next 1 year:
between adddate(curdate(), 365) and adddate(curdate(), 1)
If you know the settings in advance you can define it in a single statement:
var defaultsettings = {
ajaxsettings : { "ak1" : "v1", "ak2" : "v2", etc. },
uisettings : { "ui1" : "v1", "ui22" : "v2", etc }
};
If you don't know the values in advance you can just define the top level object and then add properties:
var defaultsettings = { };
defaultsettings["ajaxsettings"] = {};
defaultsettings["ajaxsettings"]["somekey"] = "some value";
Or half-way between the two, define the top level with nested empty objects as properties and then add properties to those nested objects:
var defaultsettings = {
ajaxsettings : { },
uisettings : { }
};
defaultsettings["ajaxsettings"]["somekey"] = "some value";
defaultsettings["uisettings"]["somekey"] = "some value";
You can nest as deep as you like using the above techniques, and anywhere that you have a string literal in the square brackets you can use a variable:
var keyname = "ajaxsettings";
var defaultsettings = {};
defaultsettings[keyname] = {};
defaultsettings[keyname]["some key"] = "some value";
Note that you can not use variables for key names in the { } literal syntax.
I think that the idea of setting the Auto Return values as described above by Kevin is a bit strange!
Say, for example, that you have a number of websites that use the same PayPal account to handle your payments, or say that you have a number of sections in one website that perform different purchasing tasks, and require different return-addresses when the payment is completed. If I put a button on my page as described above in the 'Sample form using PHP for direct payments' section, you can see that there is a line there:
input type="hidden" name="return" value="https://www.yoursite.com/checkout_complete.php"
where you set the individual return value. Why does it have to be set generally, in the profile section as well?!?!
Also, because you can only set one value in the Profile Section, it means (AFAIK) that you cannot use the Auto Return on a site with multiple actions.
Comments please??
You need to install the provisioning profile (drag and drop it into iTunes). Then drag and drop the .ipa. Ensure you device is set to sync apps, and try again.
Came across this late, but I think it could use another answer.
If you're using sass, you can actually change the variables before you import bootstrap. http://twitter.github.com/bootstrap/customize.html#variables
Change any of them, such as:
$bodyBackground: red;
@import "bootstrap";
Alternatively if there isn't a variable available for what you want to change, you can override the styles or add your own.
Sass:
@import "bootstrap";
/* override anything manually, like rounded buttons */
.btn {
border-radius: 0;
}
Also see this: Proper SCSS Asset Structure in Rails
For a shopping cart situation here's what I recommend. I'm gonna break it down into it's simplest form.
Assuming we start with this(a list view with 2 colums, 2 buttons, and a label):
First things first, removing the items, to do that we'll enter our remove button:
private void button2_Click(object sender, EventArgs e)
{
listView1.Items.Remove(listView1.SelectedItems[0]);
label1.Text = updateCartTotal().ToString();
}
Now the second line is updating our labels total using the next function i'll post to addup all the total of column 2 in the listview:
private decimal updateCartTotal()
{
decimal runningTotal = 0;
foreach(ListViewItem l in listView1.Items)
{
runningTotal += Convert.ToDecimal(l.SubItems[1].Text);
}
return runningTotal;
}
You don't have to use decimal like I did, you can use float or int if you don't have decimals. So let's break it down. We use a for loop to total all the items in the column 2(SubItems[1].Text). Add that to a decimal we declared prior to the foreach loop to keep a total. If you want to do tax you can do something like:
return runningTotal * 1.15;
or whatever your tax rate is.
Long and short of it, using this function you can retotal your listview by just calling the function. You can change the labels text like I demo'd prior if that's what you're after.
You have some syntax issues with your script. Here is a fixed version:
#!/bin/bash
if [ "$seconds" -eq 0 ]; then
timezone_string="Z"
elif [ "$seconds" -gt 0 ]; then
timezone_string=$(printf "%02d:%02d" $((seconds/3600)) $(((seconds / 60) % 60)))
else
echo "Unknown parameter"
fi
The answer is right, but it will add a listener that will be triggered every time a click occurs on your page. To avoid that, you can add the listener for just one time :
$('a#menu-link').on('click', function(e) {
e.preventDefault();
e.stopPropagation();
$('#menu').toggleClass('open');
$(document).one('click', function closeMenu (e){
if($('#menu').has(e.target).length === 0){
$('#menu').removeClass('open');
} else {
$(document).one('click', closeMenu);
}
});
});
Edit: if you want to avoid the stopPropagation()
on the initial button you can use this
var $menu = $('#menu');
$('a#menu-link').on('click', function(e) {
e.preventDefault();
if (!$menu.hasClass('active')) {
$menu.addClass('active');
$(document).one('click', function closeTooltip(e) {
if ($menu.has(e.target).length === 0 && $('a#menu-link').has(e.target).length === 0) {
$menu.removeClass('active');
} else if ($menu.hasClass('active')) {
$(document).one('click', closeTooltip);
}
});
} else {
$menu.removeClass('active');
}
});
If the number of your messages is limited then the following may help. I used jQuery for the following example, but it works with plain js too.
The innerHtml property did not work for me. So I experimented with ...
<div id=successAndErrorMessages-1>100% OK</div>
<div id=successAndErrorMessages-2>This is an error mssg!</div>
and toggled one of the two on/off ...
$("#successAndErrorMessages-1").css('display', 'none')
$("#successAndErrorMessages-2").css('display', '')
For some reason I had to fiddle around with the ordering before it worked in all types of browsers.
Try this code:
@RequestMapping(value = "/validate", method = RequestMethod.GET, produces = "application/json")
public ResponseEntity<ErrorBean> validateUser(@QueryParam("jsonInput") final String jsonInput) {
int numberHTTPDesired = 400;
ErrorBean responseBean = new ErrorBean();
responseBean.setError("ERROR");
responseBean.setMensaje("Error in validation!");
return new ResponseEntity<ErrorBean>(responseBean, HttpStatus.valueOf(numberHTTPDesired));
}
I faced the same problem too. Look up to the left side, and select (full). (Make), (gcc) and many others will appear. You will be able to chose the search bar to find them easily.
An easier way to clear a screen while in python is to use Ctrl + L though it works for the shell as well as other programs.
I tried this:
python -m pipenv # for python2
python3 -m pipenv # for python3
Hope this can help you.
this part :
"Your new price is: $"(float(price)
asks python to call this string:
"Your new price is: $"
just like you would a function:
function( some_args)
which will ALWAYS trigger the error:
TypeError: 'str' object is not callable
I had a similar issue and ended up with this:
For me this has the advantage that data and annotation are not overlapping.
from matplotlib import pyplot as plt
import numpy as np
fig = plt.figure()
ax = fig.add_subplot(111)
A = -0.75, -0.25, 0, 0.25, 0.5, 0.75, 1.0
B = 0.73, 0.97, 1.0, 0.97, 0.88, 0.73, 0.54
plt.plot(A,B)
# annotations at the side (ordered by B values)
x0,x1=ax.get_xlim()
y0,y1=ax.get_ylim()
for ii, ind in enumerate(np.argsort(B)):
x = A[ind]
y = B[ind]
xPos = x1 + .02 * (x1 - x0)
yPos = y0 + ii * (y1 - y0)/(len(B) - 1)
ax.annotate('',#label,
xy=(x, y), xycoords='data',
xytext=(xPos, yPos), textcoords='data',
arrowprops=dict(
connectionstyle="arc3,rad=0.",
shrinkA=0, shrinkB=10,
arrowstyle= '-|>', ls= '-', linewidth=2
),
va='bottom', ha='left', zorder=19
)
ax.text(xPos + .01 * (x1 - x0), yPos,
'({:.2f}, {:.2f})'.format(x,y),
transform=ax.transData, va='center')
plt.grid()
plt.show()
Using the text argument in .annotate
ended up with unfavorable text positions.
Drawing lines between a legend and the data points is a mess, as the location of the legend is hard to address.
You just add an accessor who define what you change
class Post < AR::Base
attr_reader :what_changed
before_filter :what_changed?
def what_changed?
@what_changed = changes || []
end
after_filter :action_on_changes
def action_on_changes
@what_changed.each do |change|
p change
end
end
end
These answers were helpful, but I wanted to share my answer with both the app.config part and the c# code part, so there is less guessing for the next person.
<log4net>
<appender name="SomeName" type="log4net.Appender.RollingFileAppender">

<appendToFile value="true" />
<rollingStyle value="Composite" />

Then in code:
ILog Log = LogManager.GetLogger("SomeName");
ILog SummaryLog = LogManager.GetLogger("Summary");
Log.DebugFormat("Processing");
SummaryLog.DebugFormat("Processing2"));
Here c:/Console.txt will contain "Processing" ... and \SummaryFile.log will contain "Processing2"
is you want fix XSS on input element? you can encode string before output to input field
PHP:
$str = htmlentities($str);
C#:
str = WebUtility.HtmlEncode(str);
after that output value direct to input field:
<input type="text" value="<?php echo $str" />
Here is an option using dplyr
. The %<>%
operator from magrittr
update the lhs object with the resulting value.
library(magrittr)
library(dplyr)
cols <- c("A", "C", "D", "H")
data %<>%
mutate_each_(funs(factor(.)),cols)
str(data)
#'data.frame': 4 obs. of 10 variables:
# $ A: Factor w/ 4 levels "23","24","26",..: 1 2 3 4
# $ B: int 15 13 39 16
# $ C: Factor w/ 4 levels "3","5","18","37": 2 1 3 4
# $ D: Factor w/ 4 levels "2","6","28","38": 3 1 4 2
# $ E: int 14 4 22 20
# $ F: int 7 19 36 27
# $ G: int 35 40 21 10
# $ H: Factor w/ 4 levels "11","29","32",..: 1 4 3 2
# $ I: int 17 1 9 25
# $ J: int 12 30 8 33
Or if we are using data.table
, either use a for
loop with set
setDT(data)
for(j in cols){
set(data, i=NULL, j=j, value=factor(data[[j]]))
}
Or we can specify the 'cols' in .SDcols
and assign (:=
) the rhs to 'cols'
setDT(data)[, (cols):= lapply(.SD, factor), .SDcols=cols]
I was hoping to add this as a comment to Marcus Westin's reply, but I can't find a link - maybe I need more reputation?
Anyway, thanks, I found this code snippet useful for quick debugging in IE. I have made some quick tweaks to fix a problem that stopped it working for me, also to scroll down automatically and use fixed positioning so it will appear in the viewport. Here's my version in case anyone finds it useful:
myLog = function() {
var _div = null;
this.toJson = function(obj) {
if (typeof window.uneval == 'function') { return uneval(obj); }
if (typeof obj == 'object') {
if (!obj) { return 'null'; }
var list = [];
if (obj instanceof Array) {
for (var i=0;i < obj.length;i++) { list.push(this.toJson(obj[i])); }
return '[' + list.join(',') + ']';
} else {
for (var prop in obj) { list.push('"' + prop + '":' + this.toJson(obj[prop])); }
return '{' + list.join(',') + '}';
}
} else if (typeof obj == 'string') {
return '"' + obj.replace(/(["'])/g, '\\$1') + '"';
} else {
return new String(obj);
}
};
this.createDiv = function() {
myLog._div = document.body.appendChild(document.createElement('div'));
var props = {
position:'fixed', top:'10px', right:'10px', background:'#333', border:'5px solid #333',
color: 'white', width: '400px', height: '300px', overflow: 'auto', fontFamily: 'courier new',
fontSize: '11px', whiteSpace: 'nowrap'
}
for (var key in props) { myLog._div.style[key] = props[key]; }
};
if (!myLog._div) { this.createDiv(); }
var logEntry = document.createElement('span');
for (var i=0; i < arguments.length; i++) {
logEntry.innerHTML += this.toJson(arguments[i]) + '<br />';
}
logEntry.innerHTML += '<br />';
myLog._div.appendChild(logEntry);
// Scroll automatically to the bottom
myLog._div.scrollTop = myLog._div.scrollHeight;
}
$('inputFile').parent().parent().children('td > label').hide();
can help you navigate two levels up ( to TD, to TR ) moving two levels back down ( all TD's in that TR and their LABEL tags ), applying the hide() function there.
if you want to stay at the TR level and hide them:
$('inputFile').parent().parent().hide();
… is sufficient.
you can navigate very easily through the elements using the jquery selectors.
parent is documented here: http://api.jquery.com/parent/
hide is documented here: http://api.jquery.com/hide/
create shape.xml in drawable folder
like shape.xml
<?xml version="1.0" encoding="utf-8"?>

<corners
android:bottomLeftRadius="7dp"
android:bottomRightRadius="7dp"
android:topLeftRadius="7dp"
android:topRightRadius="7dp" />

and in myactivity.xml
you can use

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/Shape"
android:background="@drawable/shape"/>
I'm a newbie to Python and the offhand comment about Python 3 in the accepted solution was confusing. For posterity, the code to do this in Python 3 is
import urllib.request
data = urllib.request.urlopen(target_url)
for line in data:
...
or alternatively
from urllib.request import urlopen
data = urlopen(target_url)
Note that just import urllib
does not work.
Further to aduchis answer above - if you then need to filter based on those group by keys, you can define a class to wrap the many keys.
return customers.GroupBy(a => new CustomerGroupingKey(a.Country, a.Gender))
.Where(a => a.Key.Country == "Ireland" && a.Key.Gender == "M")
.SelectMany(a => a)
.ToList();
Where CustomerGroupingKey takes the group keys:
private class CustomerGroupingKey
{
public CustomerGroupingKey(string country, string gender)
{
Country = country;
Gender = gender;
}
public string Country { get; }
public string Gender { get; }
}
The COM threading model is called an "apartment" model, where the execution context of initialized COM objects is associated with either a single thread (Single Thread Apartment) or many threads (Multi Thread Apartment). In this model, a COM object, once initialized in an apartment, is part of that apartment for the duration of its runtime.
The STA model is used for COM objects that are not thread safe. That means they do not handle their own synchronization. A common use of this is a UI component. So if another thread needs to interact with the object (such as pushing a button in a form) then the message is marshalled onto the STA thread. The windows forms message pumping system is an example of this.
If the COM object can handle its own synchronization then the MTA model can be used where multiple threads are allowed to interact with the object without marshalled calls.

w=open(file.txt, 'r')
print ('first line is : ',w.readline())
for line in w:
x= line
print ('last line is : ',x)
w.close()
The for
loop runs through the lines and x
gets the last line on the final iteration.
I was finding somethig for make a filter passing an Object, then i can use it like multi-filter:
i did this Beauty Solution:
filter.pipe.ts
import { PipeTransform, Pipe } from '@angular/core';
@Pipe({
name: 'filterx',
pure: false
})
export class FilterPipe implements PipeTransform {
transform(items: any, filter: any, isAnd: boolean): any {
let filterx=JSON.parse(JSON.stringify(filter));
for (var prop in filterx) {
if (Object.prototype.hasOwnProperty.call(filterx, prop)) {
if(filterx[prop]=='')
{
delete filterx[prop];
}
}
}
if (!items || !filterx) {
return items;
}
return items.filter(function(obj) {
return Object.keys(filterx).every(function(c) {
return obj[c].toLowerCase().indexOf(filterx[c].toLowerCase()) !== -1
});
});
}
}

Why are people using list slicing (slow because it copies to a new list), importing a library function, or trying to rotate an array for this?
Use a normal for-loop with range(start, stop, step)
(where start
and step
are optional arguments).
For example, looping through an array starting at index 1:
for i in range(1, len(arr)):
print(arr[i])

It is possible to define a urlBasedViewResolver
in your properties file:
excel.(class)=fi.utu.seurantaraporttisuodatin.service.Raportti
index.(class)=org.springframework.web.servlet.view.urlBasedView
index.viewClass =org.springframework.web.servlet.view.JstlView
index.prefix = /WEB-INF/jsp/
index.suffix =.jsp
You can also use btoa instead of base64.encode().
headers.set('Authorization', 'Basic ' + btoa(username + ":" + password));
This should be enough:
.nav.navbar-nav li a:hover {
color: red;
}
Putting these lines at the starting of the code will tell your operating systems to look up the binary program needed for the execution of the python script i.e it is the python interpreter.
So it depends on your operating system where it keeps the python interpreter. As I have Ubuntu as operating system it keeps the python interpreter in /usr/bin/python
so I have to write this line at the starting of my python script;
#!/usr/bin/python
After completing and saving your code
Start your command terminal
Make sure the script lies in your present working directory
Type chmod +x script_name.py
Now you can start the script by clicking the script. An alert box will appear; press "Run" or "Run in Terminal" in the alert box; or, at the terminal prompt, type ./script_name.py
You can use the substring method of the String
class that takes only the beginning index and returns the substring that begins with the character at the specified index and extending to the end of the string.
String str = "Jamaica";
str = str.substring(1);
Here's my solution, suitable for use in a PS1, or for automatically labeling a release
If you are checked out at a branch, you get the branch name.
If you are in a just init'd git project, you just get '@'
If you are headless, you get a nice human name relative to some branch or tag, with an '@' preceding the name.
If you are headless and not an ancestor of some branch or tag you just get the short SHA1.
function we_are_in_git_work_tree {
git rev-parse --is-inside-work-tree &> /dev/null
}
function parse_git_branch {
if we_are_in_git_work_tree
then
local BR=$(git rev-parse --symbolic-full-name --abbrev-ref HEAD 2> /dev/null)
if [ "$BR" == HEAD ]
then
local NM=$(git name-rev --name-only HEAD 2> /dev/null)
if [ "$NM" != undefined ]
then echo -n "@$NM"
else git rev-parse --short HEAD 2> /dev/null
fi
else
echo -n $BR
fi
fi
}
You can remove the if we_are_in_git_work_tree
bit if you like; I just use it in another function in my PS1 which you can view in full here: PS1 line with git current branch and colors
What we have done was extending org.springframework.web.context.ContextLoaderListener
to print something when the context starts.
public class ContextLoaderListener extends org.springframework.web.context.ContextLoaderListener
{
private static final Logger logger = LoggerFactory.getLogger( ContextLoaderListener.class );
public ContextLoaderListener()
{
logger.info( "Starting application..." );
}
}
Configure the subclass then in web.xml
:
<listener>
<listener-class>
com.mycomp.myapp.web.context.ContextLoaderListener
</listener-class>
</listener>
I am adding this A because I got caught with a bizarre version of this which really had me scratching my head for about a hour until I spotted the root cause. My load was failing because of multiple repeats of this format
<path>/linit.o:(.rodata1.libs+0x50): multiple definition of `lua_lib_BASE'
<path>/linit.o:(.rodata1.libs+0x50): first defined here
I turned out to be a bug in my Makefile magic where I had a list of C files and using vpath etc., so the compiles would pick them up from the correct directory in hierarchy. However one C file was repeated in the list, at the end of one line and the start of the next so the gcc load generated by the make had the .o
file twice on the command line. Durrrrh. The multiple definitions were from multiple occurances of the same file. The linker ignored duplicates apart from static initialisers!
I've been told they are the same.
Actually they are documented in the same place under ruby-doc.org:
http://www.ruby-doc.org/core/classes/Array.html#M000249
- ary.collect {|item| block } ? new_ary
- ary.map {|item| block } ? new_ary
- ary.collect ? an_enumerator
- ary.map ? an_enumerator
Invokes block once for each element of self. Creates a new array containing the values returned by the block. See also Enumerable#collect.
If no block is given, an enumerator is returned instead.a = [ "a", "b", "c", "d" ] a.collect {|x| x + "!" } #=> ["a!", "b!", "c!", "d!"] a #=> ["a", "b", "c", "d"]
You're probably passing null
value if you're loading the coordinates dynamically, set a check before you call the map loader ie: if(mapCords){loadMap}
Just think of bool? as having 3 values, then things get easier:
if (someNullableBool == true) // only if true
if (someNullableBool == false) // only if false
if (someNullableBool == null) // only if null
if((boolean1 && !boolean2) || (boolean2 && !boolean1))
{
//do it
}
IMHO this code could be simplified:
if(boolean1 != boolean2)
{
//do it
}
To indent every line in a file type, Esc and then G=gg.
Create a function and copy the code using winsock which is mentioned already by Software_Developer.
For Instance:
#ifdef _WIN32
// this is required only for windows
if (WSAStartup(MAKEWORD(2,2), &wsaData) != 0)
{
//...
}
#endif
winsock code here
#ifdef _WIN32
WSACleanup();
#endif
Use a packet analyzer to intercept the packets to/from somewhere.com
. Studying those packets should tell you what is going on.
Time-outs or connections refused could mean that the remote host is too busy.
Use an interval instead of an integer:
SELECT *
FROM table
WHERE auth_user.lastactivity > CURRENT_TIMESTAMP - INTERVAL '100 days'
I used deep:true, but found the old and new value in the watched function was the same always. As an alternative to previous solutions I tried this, which will check any change in the whole object by transforming it to a string:
created() {
this.$watch(
() => JSON.stringify(this.object),
(newValue, oldValue) => {
//do your stuff
}
);
},
Try to check it once more according to this tutorial: http://vietpad.sourceforge.net/javaonwindows.html
Try to reboot your system.
If nothing, try to run "cmd" and type there "java", does it print anything?
Simple like this:
$(function() {
...
var element = $("#selecter")
if(element.val() === element.attr("placeholder"){
element.text("").select().blur();
}
...
});
You can use some code like this, you can adjust a height and width as per your need
protected void button_Click(object sender, EventArgs e)
{
// open a pop up window at the center of the page.
ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", "var Mleft = (screen.width/2)-(760/2);var Mtop = (screen.height/2)-(700/2);window.open( 'your_page.aspx', null, 'height=700,width=760,status=yes,toolbar=no,scrollbars=yes,menubar=no,location=no,top=\'+Mtop+\', left=\'+Mleft+\'' );", true);
}
I made this jQuery extension to print the HTML of the element selected: $('#div2').print();
$.fn.extend({
print: function() {
var frameName = 'printIframe';
var doc = window.frames[frameName];
if (!doc) {
$('<iframe>').hide().attr('name', frameName).appendTo(document.body);
doc = window.frames[frameName];
}
doc.document.body.innerHTML = this.html();
doc.window.print();
return this;
}
});
See it in action here.
Using inline handlers is incompatible with Content Security Policy so the addEventListener
approach is more secure from that point of view. Of course you can enable the inline handlers with unsafe-inline
but, as the name suggests, it's not safe as it brings back the whole hordes of JavaScript exploits that CSP prevents.
[What you have is just an object, not a "json-object". JSON is a textual notation. What you've quoted is JavaScript code using an array initializer and an object initializer (aka, "object literal syntax").]
If you can rely on having ECMAScript5 features available, you can use the Object.keys
function to get an array of the keys (property names) in an object. All modern browsers have Object.keys
(including IE9+).
Object.keys(jsonData).forEach(function(key) {
var value = jsonData[key];
// ...
});
The rest of this answer was written in 2011. In today's world, A) You don't need to polyfill this unless you need to support IE8 or earlier (!), and B) If you did, you wouldn't do it with a one-off you wrote yourself or grabbed from an SO answer (and probably shouldn't have in 2011, either). You'd use a curated polyfill, possibly from es5-shim
or via a transpiler like Babel that can be configured to include polyfills (which may come from es5-shim
).
Here's the rest of the answer from 2011:
Note that older browsers won't have it. If not, this is one of the ones you can supply yourself:
if (typeof Object.keys !== "function") {
(function() {
var hasOwn = Object.prototype.hasOwnProperty;
Object.keys = Object_keys;
function Object_keys(obj) {
var keys = [], name;
for (name in obj) {
if (hasOwn.call(obj, name)) {
keys.push(name);
}
}
return keys;
}
})();
}
That uses a for..in
loop (more info here) to loop through all of the property names the object has, and uses Object.prototype.hasOwnProperty
to check that the property is owned directly by the object rather than being inherited.
(I could have done it without the self-executing function, but I prefer my functions to have names, and to be compatible with IE you can't use named function expressions [well, not without great care]. So the self-executing function is there to avoid having the function declaration create a global symbol.)
Wouldn't
apt-get install r-cran-rjava
have been easier? You could have asked me at useR! :)
Primary key -> Any column or set of columns that can uniquely identify a record in the table is a primary key. (There can be only one Primary key in the table)
Candidate key -> Any column or set of columns that are candidate to become primary key are Candidate key. (There can be one or more candidate key(s) in the table, if there is only one candidate key, it can be chosen as Primary key)
You can easily use the MODE argument:
MySQL :: MySQL 5.5 Reference Manual :: 12.7 Date and Time Functions
If the mode argument is omitted, the value of the default_week_format system variable is used:

As to your bonus question, try if (jQuery.inArray(jQuery("input:first").val(), ar) < 0)
std::string str("a string");
std::cout << str.size() << std::endl;
Basically, "assert true" will pass and "assert false" will fail. Let's looks at how this will work:
public static void main(String[] args)
{
String s1 = "Hello";
assert checkInteger(s1);
}
private static boolean checkInteger(String s)
{
try {
Integer.parseInt(s);
return true;
}
catch(Exception e)
{
return false;
}
}
Use the filter()
method in PySpark by filtering out the first column name to remove the header:
# Read file (change format for other file formats)
contentRDD = sc.textfile(<filepath>)
# Filter out first column of the header
filterDD = contentRDD.filter(lambda l: not l.startswith(<first column name>)
# Check your result
for i in filterDD.take(5) : print (i)
$date= new DateTime($row['your_date']) ;
echo $date->format('Y-m-d');
You can pass parameters into your initial java process with -D:
java -cp <classpath> -Dkey1=value -Dkey2=value ...
I found another solution for recent version of NPM. What I want to do is to replace all the "*" dependencies with the explicit lastest version number. None of the methods discussed has worked for me.
What I did:
npm-check-updates -u
Everything in package.json now is updated to the last version.
Assuming your dataframe is mydf:
mydf$task <- factor(mydf$task, levels = c("up", "down", "left", "right", "front", "back"))
If you have a hard time remembering the default values (I know I have...) here's a short extract from BalusC's answer:
Component | Submit | Refresh ------------ | --------------- | -------------- f:ajax | execute="@this" | render="@none" p:ajax | process="@this" | update="@none" p:commandXXX | process="@form" | update="@none"
Simply use the css entry of min-height to one of the cells of your table row. Works on old browsers too.

You should use BFG Repo-Cleaner.
According to the website:
The BFG is a simpler, faster alternative to git-filter-branch for cleansing bad data out of your Git repository history:
- Removing Crazy Big Files
- Removing Passwords, Credentials & other Private data
The classic procedure for reducing the size of a repository would be:
git clone --mirror git://example.com/some-big-repo.git
java -jar bfg.jar --strip-biggest-blobs 500 some-big-repo.git
cd some-big-repo.git
git reflog expire --expire=now --all
git gc --prune=now --aggressive
git push
We can use ix
to reorder by passing a list:
In [27]:
# get a list of columns
cols = list(df)
# move the column to head of list using index, pop and insert
cols.insert(0, cols.pop(cols.index('Mid')))
cols
Out[27]:
['Mid', 'Net', 'Upper', 'Lower', 'Zsore']
In [28]:
# use ix to reorder
df = df.ix[:, cols]
df
Out[28]:
Mid Net Upper Lower Zsore
Answer_option
More_than_once_a_day 2 0% 0.22% -0.12% 65
Once_a_day 3 0% 0.32% -0.19% 45
Several_times_a_week 4 2% 2.45% 1.10% 78
Once_a_week 6 1% 1.63% -0.40% 65
Another method is to take a reference to the column and reinsert it at the front:
In [39]:
mid = df['Mid']
df.drop(labels=['Mid'], axis=1,inplace = True)
df.insert(0, 'Mid', mid)
df
Out[39]:
Mid Net Upper Lower Zsore
Answer_option
More_than_once_a_day 2 0% 0.22% -0.12% 65
Once_a_day 3 0% 0.32% -0.19% 45
Several_times_a_week 4 2% 2.45% 1.10% 78
Once_a_week 6 1% 1.63% -0.40% 65
You can also use loc
to achieve the same result as ix
will be deprecated in a future version of pandas from 0.20.0
onwards:
df = df.loc[:, cols]
Angular 6 + Alyle UI
With Alyle UI you can change the styles dynamically
Here a demo stackblitz

}
),
LyCommonModule, // for bg, color, raised and others
],
bootstrap: [AppComponent]
})
export class AppModule { }

A note to romainl's answer: aliases don't work together with sudo because only the first word is checked on aliases. To change this add another alias to your .profile / .bashrc:
alias sudo='sudo '
With this change sudo vim
will behave as expected!
If you code for iOS 13.0 or later and want a timestamp, then you can use:
let currentDate = NSDate.now
Ben's code requires the parent div to have the form-group class (I was using btn-group), this is a slightly different version which just searches for the closest div and may even be a bit faster.
$(".dropdown-menu li a").click(function(){
var selText = $(this).text();
$(this).closest('div').find('button[data-toggle="dropdown"]').html(selText + ' <span class="caret"></span>');
});
Cryptography deals with numbers and strings. Basically every digital thing in the entire universe are numbers. When I say numbers, its 0 & 1. You know what they are, binary. The images you see on screen, the music that you listen through your earphone, everything are binaries. But our ears and eyes will not understand binaries right? Only brain could understand that, and even if it could understand binaries, it can’t enjoy binaries. So we convert the binaries to human understandable formats such as mp3,jpg,etc. Let’s term the process as Encoding. It’s two way process and can be easily decoded back to its original form.
Hashing
Hashing is another cryptography technique in which a data once converted to some other form can never be recovered back. In Layman’s term, there is no process called de-hashing. There are many hash functions to do the job such as sha-512, md5 and so on.
If the original value cannot be recovered, then where do we use this? Passwords! When you set up a password for your mobile or PC, a hash of your password is created and stored in a secure place. When you make a login attempt next time, the entered string is again hashed with the same algorithm (hash function) and the output is matched with the stored value. If it’s the same, you get logged in. Otherwise you are thrown out.
Credits: wikimedia By applying hash to the password, we can ensure that an attacker will never get our password even if he steal the stored password file. The attacker will have the hash of the password. He can probably find a list of most commonly used passwords and apply sha-512 to each of it and compare it with the value in his hand. It is called the dictionary attack. But how long would he do this? If your password is random enough, do you think this method of cracking would work? All the passwords in the databases of Facebook, Google and Amazon are hashed, or at least they are supposed to be hashed.
Then there is Encryption
Encryption lies in between hashing and encoding. Encoding is a two way process and should not be used to provide security. Encryption is also a two way process, but original data can be retrieved if and only if the encryption key is known. If you don’t know how encryption works, don’t worry, we will discuss the basics here. That would be enough to understand the basics of SSL. So, there are two types of Encryption namely Symmetric and Asymmetric encryption.
Symmetric Key Encryption
I am trying to keep things as simple as I could. So, let’s understand the symmetric encryption by means of a shift algorithm. This algorithm is used to encrypt alphabets by shifting the letters to either left or right. Let’s take a string CRYPTO and consider a number +3. Then, the encrypted format of CRYPTO will be FUBSWR. That means each letter is shifted to right by 3 places. Here, the word CRYPTO is called Plaintext, the output FUBSWR is called the Ciphertext, the value +3 is called the Encryption key (symmetric key) and the whole process is a cipher. This is one of the oldest and basic symmetric key encryption algorithm and its first usage was reported during the time of Julius Caesar. So, it was named after him and it is the famous Caesar Cipher. Anyone who knows the encryption key and can apply the reverse of Caesar’s algorithm and retrieve the original Plaintext. Hence it is called a Symmetric Encryption.
Asymmetric Key Encryption
We know that, in Symmetric encryption same key is used for both encryption and decryption. Once that key is stolen, all the data is gone. That’s a huge risk and we need more complex technique. In 1976, Whitfield Diffie and Martin Hellman first published the concept of Asymmetric encryption and the algorithm was known as Diffie–Hellman key exchange. Then in 1978, Ron Rivest, Adi Shamir and Leonard Adleman of MIT published the RSA algorithm. These can be considered as the foundation of Asymmetric cryptography.
As compared to Symmetric encryption, in Asymmetric encryption, there will be two keys instead of one. One is called the Public key, and the other one is the Private key. Theoretically, during initiation we can generate the Public-Private key pair to our machine. Private key should be kept in a safe place and it should never be shared with anyone. Public key, as the name indicates, can be shared with anyone who wish to send encrypted text to you. Now, those who have your public key can encrypt the secret data with it. If the key pair were generated using RSA algorithm, then they should use the same algorithm while encrypting the data. Usually the algorithm will be specified in the public key. The encrypted data can only be decrypted with the private key which is owned by you.

const app = express();
class Start {
constructor() {
const server = app.listen(8081),

I just had this exact same problem. My solution was to use temporary files since I was generating a bunch of temporary files already. The form is submitted with:
var microBox = {
show : function(content) {
$(document.body).append('<div id="microBox_overlay"></div><div id="microBox_window"><div id="microBox_frame"><div id="microBox">' +
content + '</div></div></div>');
return $('#microBox_overlay');
},
close : function() {
$('#microBox_overlay').remove();
$('#microBox_window').remove();
}
};
$.fn.bgForm = function(content, callback) {
// Create an iframe as target of form submit
var id = 'bgForm' + (new Date().getTime());
var $iframe = $('<iframe id="' + id + '" name="' + id + '" style="display: none;" src="about:blank"></iframe>')
.appendTo(document.body);
var $form = this;
// Submittal to an iframe target prevents page refresh
$form.attr('target', id);
// The first load event is called when about:blank is loaded
$iframe.one('load', function() {
// Attach listener to load events that occur after successful form submittal
$iframe.load(function() {
microBox.close();
if (typeof(callback) == 'function') {
var iframe = $iframe[0];
var doc = iframe.contentWindow.document;
var data = doc.body.innerHTML;
callback(data);
}
});
});
this.submit(function() {
microBox.show(content);
});
return this;
};
$('#myForm').bgForm('Please wait...');
At the end of the script that generates the file I have:
header('Refresh: 0;url=fetch.php?token=' . $token);
echo '<html></html>';
This will cause the load event on the iframe to be fired. Then the wait message is closed and the file download will then start. Tested on IE7 and Firefox.
If it's a maven project, go to file>import>maven project >existing maven project, then browse for the folder that contains the project, select folder then click finish. That worked for me
UPDATE
If you are working in a particular project I highly recommend using editorconfig.
It lets you define an .editorconfig
file at the root of your repository defining the indentation you want to use for each file type across your repository.
For example:
root = true
[*.css]
charset = utf-8
indent_style = space
indent_size = 4
[*.js]
charset = utf-8
indent_style = space
indent_size = 2
There is a vim plugin that automatically configures vim according to the config file for file you open.
On top of that the .editorconfig
file is automatically supported on many other IDEs and editors so it is the best option for collaborating between users with different environments.
ORIGINAL ANSWER
If you need to change sizes often and you don't want to bind this to a specific file type you can have predefined commands on your .vimrc file to quickly switch preferences:
nmap <leader>t :set expandtab tabstop=4 shiftwidth=4 softtabstop=4<CR>
nmap <leader>m :set expandtab tabstop=2 shiftwidth=2 softtabstop=2<CR>
This maps two different sets of sizes to keys \t and \m. You can rebind this to whatever keys you want.
Test-Path may give odd answer. E.g. "Test-Path c:\temp\ -PathType leaf" gives false, but "Test-Path c:\temp* -PathType leaf" gives true. Sad :(
You don't need a controller and when using .Net 5 (MVC 6) you can render the partial view async
@await Html.PartialAsync("_LoginPartial")
or
@{await Html.RenderPartialAsync("PartialName");}
or if you are using .net core 2.1 > you can just use:
<partial name="Shared/_ProductPartial.cshtml"
for="Product" />
Pre-increment ++i increments the value of i and evaluates to the new incremented value.
int i = 3;
int preIncrementResult = ++i;
Assert( preIncrementResult == 4 );
Assert( i == 4 );
Post-increment i++ increments the value of i and evaluates to the original non-incremented value.
int i = 3;
int postIncrementResult = i++;
Assert( postIncrementtResult == 3 );
Assert( i == 4 );
In C++, the pre-increment is usually preferred where you can use either.
This is because if you use post-increment, it can require the compiler to have to generate code that creates an extra temporary variable. This is because both the previous and new values of the variable being incremented need to be held somewhere because they may be needed elsewhere in the expression being evaluated.
So, in C++ at least, there can be a performance difference which guides your choice of which to use.
This is mainly only a problem when the variable being incremented is a user defined type with an overridden ++ operator. For primitive types (int, etc) there's no performance difference. But, it's worth sticking to the pre-increment operator as a guideline unless the post-increment operator is definitely what's required.
There's some more discussion here.
In C++ if you're using STL, then you may be using for loops with iterators. These mainly have overridden ++ operators, so sticking to pre-increment is a good idea. Compilers get smarter all the time though, and newer ones may be able to perform optimizations that mean there's no performance difference - especially if the type being incremented is defined inline in header file (as STL implementations often are) so that the compiler can see how the method is implemented and can then know what optimizations are safe to perform. Even so, it's probably still worth sticking to pre-increment because loops get executed lots of times and this means a small performance penalty could soon get amplified.
In other languages such as C# where the ++ operator can't be overloaded there is no performance difference. Used in a loop to advance the loop variable, the pre and post increment operators are equivalent.
Correction: overloading ++ in C# is allowed. It seems though, that compared to C++, in C# you cannot overload the pre and post versions independently. So, I would assume that if the result of calling ++ in C# is not assigned to a variable or used as part of a complex expression, then the compiler would reduce the pre and post versions of ++ down to code that performs equivalently.
You need use Stream to send file (archive) in a response, what is more you have to use appropriate Content-type in your response header.
There is an example function that do it:
const fs = require('fs');
// Where fileName is name of the file and response is Node.js Reponse.
responseFile = (fileName, response) => {
const filePath = "/path/to/archive.rar" // or any file format
// Check if file specified by the filePath exists
fs.exists(filePath, function(exists){
if (exists) {
// Content-type is very interesting part that guarantee that
// Web browser will handle response in an appropriate manner.
response.writeHead(200, {
"Content-Type": "application/octet-stream",
"Content-Disposition": "attachment; filename=" + fileName
});
fs.createReadStream(filePath).pipe(response);
} else {
response.writeHead(400, {"Content-Type": "text/plain"});
response.end("ERROR File does not exist");
}
});
}
}
The purpose of the Content-Type field is to describe the data contained in the body fully enough that the receiving user agent can pick an appropriate agent or mechanism to present the data to the user, or otherwise deal with the data in an appropriate manner.
"application/octet-stream" is defined as "arbitrary binary data" in RFC 2046, purpose of this content-type is to be saved to disk - it is what you really need.
"filename=[name of file]" specifies name of file which will be downloaded.

You want to (1) create stdout output in one process (like echo '…'
) and (2) redirect that output to stdin input of another process but (3) without the use of the bash pipe mechanism. Here's a solution that matches all three conditions:
/my/bash/script < <(echo 'This string will be sent to stdin.')
The <
is normal input redirection for stdin. The <(…)
is bash process substitution. Roughly it creates a /dev/fd/…
file with the output of the substituting command and passes that filename in place of the <(…)
, resulting here for example in script < /dev/fd/123
. For details, see this answer.
A one-line heredoc sent to stdin script <<< 'string'
only allows to send static strings, not the output of other commands.
Process substitution alone, such as in diff <(ls /bin) <(ls /usr/bin)
, does not send anything to stdin. Instead, the process output is saved into a file, and its path is passed as a command line argument. For the above example, this is equivalent to diff /dev/fd/10 /dev/fd/11
, a command where diff
receives no input from stdin.
I like that, unlike the pipe mechanism, the < <(…)
mechanism allows to put the command first and all input after it, as is the standard for input from command line options.
However, beyond commandline aesthetics, there are some cases where a pipe mechanism cannot be used. For example, when a certain command has to be provided as argument to another command, such as in this example with sshpass
.
The right mental model for using mutexes: The mutex protects an invariant.
Why are you sure that this is really right mental model for using mutexes? I think right model is protecting data but not invariants.
The problem of protecting invariants presents even in single-threaded applications and has nothing common with multi-threading and mutexes.
Furthermore, if you need to protect invariants, you still may use binary semaphore wich is never recursive.

Multiple inheritance is one of those things that generally causes more problems than it solves. In C++ it fits the pattern of giving you enough rope to hang yourself, but Java and C# have chosen to go the safer route of not giving you the option. The biggest problem is what to do if you inherit multiple classes that have a method with the same signature that the inheritee doesn't implement. Which class's method should it choose? Or should that not compile? There is generally another way to implement most things that doesn't rely on multiple inheritance.
You can look at sorting the string -- treat it as a char array -- and then do a modified binary search which counts occurrences? But I agree with @tofutim that traversing it is the most efficient -- O(N) versus O(N * logN) + O(logN)
If you're using knockout.bindings.dataTables.js
then you can edit the file and replace this line
dataTable.fnAddData(unwrappedItems);
with
if (unwrappedItems.length > 0) {
dataTable.fnAddData(unwrappedItems);
}
This has help me and i hope will help you.

Just porting over the Java from Compute hex color code for an arbitrary string to Javascript:
function hashCode(str) { // java String#hashCode

}
return hash;

var c = (i & 0x00FFFFFF)

.toUpperCase();
return "00000".substring(0, 6 - c.length) + c;

To convert you would do:
intToRGB(hashCode(your_string))
I found this suggestion useful in my case:
def product_params
params.require(:product).permit(:name).tap do |whitelisted|
whitelisted[:data] = params[:product][:data]
end
end
Check this link of Xavier's comment on github.
This approach whitelists the entire params[:measurement][:groundtruth] object.
Using the original questions attributes:
def product_params
params.require(:measurement).permit(:name, :groundtruth).tap do |whitelisted|
whitelisted[:groundtruth] = params[:measurement][:groundtruth]
end
end
It is simplified a lot in version Java 8. I have given some util methods below.
To get the day of the month in the format of
int
for the given day, month, and year.
public static int findDay(final int month, final int day, final int year) {
// System.out.println(LocalDate.of(year, month, day).getDayOfMonth());
return LocalDate.of(year, month, day).getDayOfMonth();
}
To get current day of the month in the format of
int
.
public static int findDay(final int month, final int day, final int year) {
// System.out.println(LocalDate.now(ZoneId.of("Asia/Kolkata")).getDayOfMonth());
return LocalDate.now(ZoneId.of("Asia/Kolkata")).getDayOfMonth();
}
To get the day of the week in the format of
String
for the given day, month, and year.
public static String findDay(final int month, final int day, final int year) {
// System.out.println(LocalDate.of(year, month, day).getDayOfWeek());
return LocalDate.of(year, month, day).getDayOfWeek().toString();
}
To get current day of the week in the format of
String
.
public static String findDay(final int month, final int day, final int year) {
// System.out.println(LocalDate.now(ZoneId.of("Asia/Kolkata"))..getDayOfWeek());
return LocalDate.now(ZoneId.of("Asia/Kolkata")).getDayOfWeek().toString();

The F5 Refresh has the semantic of "please reload the current HTML AND its direct dependancies". Hence you should expect to see any imgs, css and js resource directly referenced by the HTML also being refetched. Of course a 304 is an acceptable response to this but F5 refresh implies that the browser will make the request rather than rely on fresh cache content.
Instead try simply navigating somewhere else and then navigating back.
You can force the refresh, past a 304, by holding ctrl while pressing f5 in most browsers.
From python 3.4.4, you can use multiprocessing.get_context() to obtain a context object to use multiple start methods:
import multiprocessing as mp
def foo(q, h, w):
q.put(h + ' ' + w)
print(h + ' ' + w)
if __name__ == '__main__':
ctx = mp.get_context('spawn')
q = ctx.Queue()
p = ctx.Process(target=foo, args=(q,'hello', 'world'))
p.start()
print(q.get())
p.join()
Or you just simply replace
pool.map(harvester(text,case),case, 1)
by:
pool.apply_async(harvester(text,case),case, 1)
this will work as well
require_once(realpath($_SERVER["DOCUMENT_ROOT"]) .'/mysite/php/includes/dbconn.inc');
Due to the bugs found by JasperV — good points! — I have rewritten my old code. I guess I only ever used this for positive values with two decimal places.
Depending on what you are trying to achieve, you may want rounding or not, so here are two versions split across that divide.
I've introduced the toFixed()
method as it better handles rounding to specific decimal places accurately and is well support. It does slow things down however.
This version still detaches the decimal, but using a different method than before. The w|0
part removes the decimal. For more information on that, this is a good answer. This then leaves the remaining integer, stores it in k
and then subtracts it again from the original number, leaving the decimal by itself.
Also, if we're to take negative numbers into account, we need to while loop (skipping three digits) until we hit b
. This has been calculated to be 1 when dealing with negative numbers to avoid putting something like -,100.00
The rest of the loop is the same as before.
function formatThousandsWithRounding(n, dp){
var w = n.toFixed(dp), k = w|0, b = n < 0 ? 1 : 0,
u = Math.abs(w-k), d = (''+u.toFixed(dp)).substr(2, dp),
s = ''+k, i = s.length, r = '';
while ( (i-=3) > b ) { r = ',' + s.substr(i, 3) + r; }
return s.substr(0, i + 3) + r + (d ? '.'+d: '');
};
In the snippet below you can edit the numbers to test yourself.

This takes a different route and attempts to avoid mathematical calculation (as this can introduce rounding, or rounding errors). If you don't want rounding, then you are only dealing with things as a string i.e. 1000.999 converted to two decimal places will only ever be 1000.99 and not 1001.00.
This method avoids using .split()
and RegExp()
however, both of which are very slow in comparison. And whilst I learned something new from Michael's answer about toLocaleString
, I also was surprised to learn that it is — by quite a way — the slowest method out of them all (at least in Firefox and Chrome; Mac OSX).
Using lastIndexOf()
we find the possibly existent decimal point, and from there everything else is pretty much the same. Save for the padding with extra 0s where needed. This code is limited to 5 decimal places. Out of my test this was the faster method.

I'll update with an in-page snippet demo shortly, but for now here is a fiddle:
https://jsfiddle.net/bv2ort0a/2/
Why use RegExp for this? — don't use a hammer when a toothpick will do i.e. use string manipulation:
var formatThousands = function(n, dp){
var s = ''+(Math.floor(n)), d = n % 1, i = s.length, r = '';
while ( (i -= 3) > 0 ) { r = ',' + s.substr(i, 3) + r; }
return s.substr(0, i + 3) + r +
(d ? '.' + Math.round(d * Math.pow(10, dp || 2)) : '');
};
formatThousands( 1000000.42 );
First strip off decimal:
s = '1000000', d = ~ 0.42
Work backwards from the end of the string:
',' + '000'
',' + '000' + ',000'
Finalise by adding the leftover prefix and the decimal suffix (with rounding to dp
no. decimal points):
'1' + ',000,000' + '.42'
One option would be to pass the whole array and the start and end indices, and iterate between those instead of iterating over the whole array passed.
void method1(byte[] array) {
method2(array,4,5);
}
void method2(byte[] smallarray,int start,int end) {
for ( int i = start; i <= end; i++ ) {
....
}
}
The accepted answer is the correct one.
OTOH, the way I previously solved this was to add the following to all projects:
test.onlyIf { ! Boolean.getBoolean('skip.tests') }
Run the build with -Dskip.tests=true
and all test tasks will be skipped.
I think you want to put a
, in front of a:link
(a
, a:link
) in your CSS file. The only way I could get rid of that awful default blue link color. I'm not sure if this was necessary for earlier version of the browsers we have, because it's supposed to work without a
So.. I had noticed in event viewer that this crash corresponded to a "System.IO.FileNotFoundException" error.
So I fired ProcMon and noticed that one of the program dlls was failing to load vcruntime140. So I simply installed vs15 redist and it worked.
I found an easy solution
Step1. connect to DB with an admin user using PLSQL or sqldeveloper or any other query interface
Step2. run the script bellow; in the S.SQL_TEXT column, you will see the executed queries
SELECT
S.LAST_ACTIVE_TIME,
S.MODULE,
S.SQL_FULLTEXT,
S.SQL_PROFILE,
S.EXECUTIONS,
S.LAST_LOAD_TIME,
S.PARSING_USER_ID,
S.SERVICE
FROM
SYS.V_$SQL S,
SYS.ALL_USERS U
WHERE
S.PARSING_USER_ID=U.USER_ID
AND UPPER(U.USERNAME) IN ('oracle user name here')
ORDER BY TO_DATE(S.LAST_LOAD_TIME, 'YYYY-MM-DD/HH24:MI:SS') desc;
The only issue with this is that I can't find a way to show the input parameters values(for function calls), but at least we can see what is ran in Oracle and the order of it without using a specific tool.
You should have sdiff
for side-by-side merge of file differences. Take a read of man sdiff
for the full story.
You can use the PHP function apc_clear_cache
.
Calling apc_clear_cache()
will clear the system cache and calling apc_clear_cache('user')
will clear the user cache.
From the documentation I get the impression that in your example it would be intended to use:
@Range(min= SEQ_MIN_VALUE, max= SEQ_MAX_VALUE)
Checks whether the annotated value lies between (inclusive) the specified minimum and maximum. Supported data types:
BigDecimal, BigInteger, CharSequence, byte, short, int, long and the respective wrappers of the primitive types
One way - split you image into N rotating it slightly every time. I'd say 5 is enough. then create something like this in drawable
<animation-list android:id="@+id/handimation" android:oneshot="false"
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/progress1" android:duration="150" />
<item android:drawable="@drawable/progress2" android:duration="150" />
<item android:drawable="@drawable/progress3" android:duration="150" />
</animation-list>
code start
progress.setVisibility(View.VISIBLE);
AnimationDrawable frameAnimation = (AnimationDrawable)progress.getDrawable();
frameAnimation.setCallback(progress);
frameAnimation.setVisible(true, true);
code stop
AnimationDrawable frameAnimation = (AnimationDrawable)progress.getDrawable();
frameAnimation.stop();
frameAnimation.setCallback(null);
frameAnimation = null;
progress.setVisibility(View.GONE);

Any future date in JavaScript (postman test uses JavaScript) can be retrieved as:
var dateNow = new Date();
var twoWeeksFutureDate = new Date(dateNow.setDate(dateNow.getDate() + 14)).toISOString();
postman.setEnvironmentVariable("future-date", twoWeeksFutureDate);
Use itertools.combinations(mylist, 2)
mylist = range(5)
for x,y in itertools.combinations(mylist, 2):
print x,y
0 1
0 2
0 3
0 4
1 2
1 3
1 4
2 3
2 4
3 4
If you have installed the Portable version of Chrome, or have it installed in a custom directory - the extensions won't be available in directory referenced in above answers.
Try right-clicking on Chrome's shortcut & Check the "Target" directory. From there, navigate to one directory above and you should be able to see the User Data
folder and then can use the answers mentioned above
The compiler doesn't know that Environment.Exit() does not return. Why not just "return" from Main()?
use explode() .
Example from the docs.
// Example 1
$pizza = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
echo $pieces[0]; // piece1
echo $pieces[1]; // piece2
note that explode has a limit function. So you could do something like
$message = implode(" ", explode(" ", $long_message, 20));
I prefer the solution suggested here, as exemplified by this jsfiddle:
CSS:
sup, sub {
vertical-align: baseline;
position: relative;
top: -0.2em;
}
sub {
top: 0.2em;
}
HTML:
<span>The following equation is perhaps the most well known of all: </span><span id="box">E<sub>a</sub> = mc<sup>2</sup></span><span>. And it gives an opportunity to try out a superscript and even throw in a superfluous subscript! I'm sure that Einstein would be pleased.</span>.
The beauty of this solution is that you can tailor the vertical positioning of the superscript and subscript, to avoid any clashes with the line above or below... in the above, just increase or decrease the 0.2em
to suit your requirements.
If a project creates a jar of the project sources and deploys it to a maven repository, then you'll find it :)
Just FYI, sources artifacts are generally created by the maven-source-plugin. This plugin can bundle the main or test sources of a project into a jar archive and, as explained in Configuring Source Plugin:
(...) The generated jar file will be named by the value of the
finalName
plus "-sources" if it is the main sources. Otherwise, it would befinalName
plus "-test-sources" if it is the test sources.
The additional text was given to describe an artifact ("-sources" or "-test-sources" here) is called a classifier.
To declare a dependency on an artifact that uses a classifier, simply add the <classifier>
element. For example:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate</artifactId>
<version>3.2.7.ga</version>
<classifier>sources</classifier>
</dependency>
Note that you generally don't do this, most IDEs provide support to download sources (and/or JavaDoc) from the main artifact without declaring explicitly a dependency on them.
Finally, also note that some repository search engines allow searching for artifacts using the classifier (at least Nexus does with the advanced search). See this search for example.
use this one:

Seems to be a bug. Usage of a spawn() trick instead of the plain fork()/exec() is advised.
Are you moving it using svn mv
, or just mv
? I think using just mv
may cause this issue.
Very quick Interface Builder solution:
For any number of views to be evenly spaced within a superview, simply give each an "Align Center X to superview" constraint for horizontal layout, or "Align Center Y superview" for vertical layout, and set the Multiplier to be N:p
(NOTE: some have had better luck with p:N
- see below)
where
N = total number of views
, and
p = position of the view including spaces
First position is 1, then a space, making the next position 3, so p becomes a series [1,3,5,7,9,...]. Works for any number of views.
So, if you have 3 views to space out, it looks like this:
EDIT Note: The choice of N:p
or p:N
depends on the relation order of your alignment constraint. If "First Item" is Superview.Center, you may use p:N
, while if Superview.Center is "Second Item", you may use N:p
. If in doubt, just try both out... :-)
Try this code, this’ll work:
-moz-transform: scale(2);
You can refer to this.
For CUDA 6.5 (and apparently 7.0 and 7.5), I've created a version of the gcc 4.8.5 RPM package (under Fedora Core 30) that allows that version of gcc to be install alongside your system's current GCC.
You can find all of that information here.
Being on jupyter notebook it works for me including the relative path only. For example:
df = pd.read_csv ('file.csv')
But, for example, in vscode I have to put the complete path:
df = pd.read_csv ('/home/code/file.csv')
This would be correct:
SELECT * FROM table WHERE field regexp concat_ws("|",(
"111",
"222",
"333"
));
To use Enum with any type of value, try this:
Updated with some improvements... Thanks @Jeff, by your tip!
from enum import Enum
class Color(Enum):
RED = 1
GREEN = 'GREEN'
BLUE = ('blue', '#0000ff')
@staticmethod
def list():
return list(map(lambda c: c.value, Color))
print(Color.list())
As result:
[1, 'GREEN', ('blue', '#0000ff')]
Along the same lines as @Eric's answer, but without using a 'NULL'
symbol.
(Field1 = Field2) OR (ISNULL(Field1, Field2) IS NULL)
This will be true only if both values are non-NULL
, and equal each other, or both values are NULL
